Deep Mapping of Small Solar System Bodies with Galactic Cosmic Ray Secondary Particle Showers

Completed Technology Project

Project Introduction

We propose to develop new types of spacecraft instrumentation, data analysis, and imaging methods that enable mapping the interior of small solar system bodies (SSBs, e.g. asteroids, comet cores and near Earth objects) to unprecedented depth and detail. Our proposed method makes use of galactic cosmic ray (GCR) secondary particle shower products, such as pions and muons.
